Aus dem Protokoll ist ersichtlich, dass die Häufigkeit der Trennung und Wiederverbindung sehr hoch ist und alle zehn Millisekunden eine Verbindung hergestellt wird.

6. Gründe

Es liegt ein Problem mit der Lastausgleichsstrategie des Nginx-Clusters vor. Da keine test_socket集群Strategie angegeben ist, verwendet Nginx standardmäßig diese轮询策略

Warum führt die Polling-Strategie dazu, dass der Socket ständig neu verbunden wird?

Dies liegt daran, dass der WebSocket-Protokoll-Handshake-Prozess nicht in einem Schritt erfolgt. Er ist in mehrere Schritte unterteilt. Wenn beim letzten Mal Server 1 die Hand geschüttelt wurde und beim nächsten Mal Server 2 die Hand geschüttelt wurde, dann der Handshake-Prozess wird definitiv nicht normal abgeschlossen, und die Verbindung wird nicht hergestellt. Sie kann nicht normal hergestellt werden.

7. Lösen

Da der Grund darin liegt, dass die Socket-Verbindung nicht mit dem festen Server kommunizieren kann, lösen Sie einfach dieses Problem.

1. Geben Sie die Lastausgleichsstrategie für den Socket-Cluster an:ip_hash

## socket集群
upstream test_socket {
    
    
	# ip_hash：根据IP地址决定具体访问的服务器
	ip_hash;
	server 192.168.1.233:9901;
	server 192.168.1.243:9901;
}

2. Starten Sie Nginx neu
